Bitfinex asks for 64 character payment ID to withdraw, but the wallet generates shorter ones

When withdrawing Monero from Bitfinex, they ask for a 64 character payment ID. The payment IDs generated by the official wallet are much too short. Should I be using the integrated address, with no payment ID?

How is the commitment for a previous outpoint computed (tx v2)?
